Substructural fuzzy logics
Substructural fuzzy logics are substructural logics that are complete with respect to algebras whose lattice reduct is the real unit interval [0, 1]. In this paper, we introduce Un...

Partial automorphism semigroups
Abstract. We study the relationship between algebraic structures and their inverse semigroups of partial automorphisms. We consider a variety of classes of natural structures inclu...

On the complexity of the resolvent representation of some prime differential ideals
We prove upper bounds on the order and degree of the polynomials involved in a resolvent representation of the prime differential ideal associated with a polynomial differential s...

Constructive Logic with Strong Negation as a Substructural Logic
Gentzen systems are introduced for Spinks and Veroff's substructural logic corresponding to constructive logic with strong negation, and some logics in its vicinity. It has b...

Tunstall code, Khodak variations, and random walks
A variable-to-fixed length encoder partitions the source string into variable-length phrases that belong to a given and fixed dictionary. Tunstall, and independently Khodak, desig...
